Setting The Line Card To E3 Or T3 Mode; Changing The Mode Of The Line Card - Cisco 10000 Series Configuration Manual

Line Card Commands

Setting the Line Card to E3 or T3 mode

You must configure the 8-Port E3/DS3 ATM line card for either E3 or T3 from interface configuration
mode.
When you configure the 8-Port E3/DS3 ATM line card for E3 or T3, all 8 ports of the line card operate
Note
in the mode you have selected.
atm dsx3mode {e3 | t3}{adm | plcp}
Where:
adm means ATM direct mapping
plcp means physical layer convergence procedure (PLCP)—specifications that map ATM cells into
physical media, such as T3 or E3, and define certain management information.
The default is t3 adm.
In the following example, the 8-Port E3/DS3 ATM line card located in slot 2 is configured for E3 mode
with PLCP:
Router(config)# interface atm 2/0/0
Router(config-if)# atm dsx3mode e3 plcp

Changing the Mode of the Line Card

The 8-Port E3/DS3 ATM line card has four modes (e3 adm, e3 plcp, t3 adm and t3 plcp), the default
mode being t3 adm. Each mode has it own bandwidth and cell delay variation tolerance (CDVT) values.
When a line card is freshly inserted, the default mode of the card can be changed. However, if VCs, VPs
or subinterfaces have already been configured on the line card, the line card must first be removed and
reprovisioned prior to the mode change.
To change the mode of an already provisioned card use the following commands in the configuration
mode:
hw-module slot <> shut
no card <>
no hw-module slot <> shut
After the line card is restarted you can change the mode, and re-apply the configurations that were lost
during module shutdown.
The following example shows how to change the mode of an already provisioned card, from E3 mode
with ADM to E3 mode with PLCP.
Router(config)# hw-module slot 2/0 shut
Router(config)# no card 2/0
Router(config)# no hw-module slot 2/0 shut
To change the mode of the line card:
Router(config)# interface atm 2/0/0
Router(config-if)# atm dsx3mode e3 plcp
To re-apply the configurations to the line card:
Router(config)#interface atm 2/0/0.1 point-to-point
Router(config-subif)#pvc 1/100
Router(config-if-atm-vc)#vbr-nrt 4000 4000
